HD 143361 b
HD 143361 b is an extrasolar planet located approximately 194 light-years away in the constellation of Norma, orbiting the 9th magnitude G-type main sequence star HD 143361. This planet has a minimum mass of 3.0 times that of Jupiter. Because the inclination is not known, the true mass is not known. This planet orbits at a distance of 2.0 AU with an orbital eccentricity of 0.18.
